Ultra-highly sensitive UV photodetector based on organic-metal hybrid structure |
| 초록 |
We demonstrate the enhancement of the photoluminescence (PL) and photodetector characteristics of light-emitting organic crystal microwires (OCMs) through incorporated with nanoscale metals. We observed nanoscale laser confocal microscope (LCM) PL intensity and spectra of the OCMs drastically varied with metal nanoparticles (NPs). We analyze that the huge enhancement PL of the hybrid OCM might originate from energy transfer and/or charge transfer in a surface plasmon resonance (SPR) coupling, supported by ultraviolet and visible absorption spectra. It is remarked that the effective SPR coupling between organic crystal and nanoscale metals can be significantly activating luminescence performance, since the strong excitation may occur optical activation. These outstanding photonic performances may be applied to developing UV and IR photo-detector. |
